Kolo Toure - Arsenal stars that strengthened their rivals

Left Arsenal to join moneybags Man City for £14m in 2009 to win trophies again
after seeing the well run dry at the Emirates after seven years of service
where he won the FA Cup twice and the Premier League title in his early
years. "I am at City because this football club wants to be on the top
and, if you want to get to the top, then you need to have players who are
capable of getting you there. The only thing you can bring players in with
is money or, if you are like Arsenal, you wait for your youngsters to come
in, but that can take a while."
